Data Error Log.
The Data Error Log includes the following fields: Logical Block Address,
Error Type, Count, and Error.
The Logical Block Address field contains the logical block address of a data block that
encountered multiple read retries during one or more data error recovery attempts.
The Error Type field indicates the type of data error the block encountered (refer to
Table 5-46).
The Count field is incremented each time a block is uncorrectable or requires multiple retries
during a transaction. This field is incremented only once for each data recovery attempt.
The Error field contains encoded data error byte information as listed in Table 5-46.

Hardware Error Log.
The Hardware Error Log includes the following fields: Logical Block
Address, Internal Drive Status, and Access Count.
The Logical Block Address field contains the logical block address of a data block that was
being accessed when the error occurred.
The Internal Device Status field contains an error code corresponding to the Additional Sense
Code field returned by the REQUEST SENSE command.
The Access Count field indicates the number of media accesses that had been performed when
the hardware fault occurred. To determine the total number of media accesses, add these
values to the Access Count field of the Usage Log. Table 5-45 lists the access count ranges
corresponding to the values in this field.
